Sr. RF Engineer

The role

You will design, implement, test, and optimize RF systems for a next-generation GNSS system. This includes work on spacecraft payload electronics and ground monitoring systems.

What you will do

• Design, implement, test, and optimize RF systems
• Work on spacecraft payload electronics and ground monitoring systems
• Ensure the end-to-end RF broadcast system delivers high-accuracy and high-precision PNT service
• Travel to support off-site testing events as needed

Required qualifications

• Understanding of electromagnetic principles behind radio frequency communications
• Ability to interpret PCBA schematics and layout drawings
• Familiarity with PCB ECAD tools such as Altium
• Hands-on experience using electrical/RF test equipment, including multimeters, oscilloscopes, signal generators, and spectrum analyzers
• Knowledge of typical performance metrics for RF communications systems
• Hands-on experience/coursework with antenna design and/or testing
• Familiarity with 3D EM simulations tools such as Ansys HFSS
• RF amplifier and circuits tuning
• RF Design experience in L-Band, S-Band and C Band
• Familiarity with RF circuit simulation tools, such as Keysight ADS or AWR Microwave Office
• Hands-on experience with RF test set-ups and calibrations
• Ability to analyze and interpret RF test data, and assess performance vs. design requirements

Nice to have

• 3 - 5 years of RF engineering experience
• Experience with space RF electronics, with an understanding of phenomena such as multipaction
• Knowledge/experience with GNSS systems
• Proven RF PCB and/or antenna designs from past work
• Implementation of passive or active RF sub-systems whether on the bench or on PCBs
